probsoln v3.04: creating problem
-sheets optionally with solutions
-
-
2012-08-23

- Contents

-
- 1 Introduction
-The probsoln package is designed for teachers or lecturers who want to
-create problem sheets for their students. This package was designed with
-mathematics problems in mind, but can be used for other subjects as well. The
-idea is to create a file containing a large number of problems with their
-solutions which can be read in by LATEX, and then select a number of
-problems to typeset. This means that once the database has been set up,
-each year you can easily create a new problem sheet that is sufficiently
-different from the previous year, thus preventing the temptation of current
-students seeking out the previous year’s students, and checking out their
-answers. There is also an option that can be passed to the package
-to determine whether or not the solutions should be printed. In this
-way, one file can either produce the student’s version or the teacher’s
-version.
-
-
-Top
2 Package Options
-The following options may be passed to this package:
-
-
-answers
- Show the answers
-
-
-noanswers
- Don’t show the answers (default)
-
-
-draft
- Display the label and dataset name when a problem is used
-
-
-final
- Don’t display label and dataset name when a problem is used
-
-
-usedefaultargs
- Make \thisproblem use the default arguments supplied in
- the problem definition.
-
-
-
-
-nousedefaultargs
- Make \thisproblem prompt for problem arguments
- (default).
-
-

3 Verbatim
-As from version 3.02, problems and solutions may contain verbatim text, but
-you must use the fragile (or fragile=true) option for the associated
-environments.
-
Alternatively, if most of your problems contain verbatim, you can globally set
-this option using:
-
-
-
-
-\setkeys{probsoln}{fragile}
-
- You can switch off this option using fragile=false.
-
The fragile option writes information to a temporary file. This defaults to
-\jobname.vrb but the name may be changed. The extension (.vrb) is given
-by:
-
\ProbSolnFragileExt \ProbSolnFragileExt
-
-The base name (\jobname) is given by:
-
\ProbSolnFragileFile \ProbSolnFragileFile
-
-
-
-Top
4 Showing and Hiding Solutions
-In addition to the answers and noanswers package options, it is also possible to
-show or suppress the solutions using
-
\showanswers \showanswers
-
-and
-
\hideanswers \hideanswers
-
-respectively.
-
The boolean variable showanswers determines whether the answers should be
-displayed. You can use this value with the ifthen package to specify
-different text depending on whether the solutions should be displayed. For
-example:
-
-
-
-
-Assignment 1\ifthenelse{\boolean{showanswers}}{ (Solution Sheet)}{}
-
- Alternatively you can use \ifshowanswers…\else…\fi:
-
-
-
-
-Assignment 1\ifshowanswers\space (Solution Sheet)\fi
-
-
-
For longer passages, you can use the environments
-
onlyproblem \begin{⟨onlyproblem⟩}[⟨option⟩]
-
-and
-
onlysolution \begin{⟨onlysolution⟩}[⟨option⟩]
-
-For example:
-
-
-
-
-\begin{onlyproblem}%
-
What is the derivative of $f(x) = x^2$?
-
\end{onlyproblem}%
-
\begin{onlysolution}%
-
$f’(x) = 2x$
-
\end{onlysolution}
-
- The above will only display the question if showanswers is false and will only
-display the solution if showanswers is true. If you want the question to appear in
-the answer sheet as well as the solution, then don’t put the question in the
-onlyproblem environment:
-
-
-
-
-What is the derivative of $f(x) = x^2$?
-
\begin{onlysolution}%
-
Solution: $f’(x) = 2x$
-
\end{onlysolution}
-
-
-
If you want to include verbatim text in the body of
onlyproblem or
-
onlysolution, you need to specify
fragile in the optional argument of the
-environment. (See
§3 Verbatim for further details.)
-
-
If you use onlysolution within the defproblem environment, the problem will
-be tagged as having a solution and will be added to the list used by
-\foreachsolution. The optional argument of onlysolution (and onlyproblem) is
-inherited from the parent defproblem setting.
-
-

5 General Formatting Commands
-The commands and environments described in this section are provided to assist
-formatting problems and their solutions.
-
solution \begin{solution}⟨text⟩\end{solution}
-
-By default, this is equivalent to
-
\par\noindent\textbf{\solutionname}: ⟨text⟩
-
-where \solutionname \solutionname defaults to “Solution”. Note that you
-must place the solution environment inside the onlysolution environment or
-between \ifshowanswers…\fi to ensure that it is suppressed when the solutions
-are not wanted. (See §4 Showing and Hiding Solutions.)
-
Note that the probsoln package will only define the solution environment if it
-is not already defined.
-
textenum \begin{textenum}…\end{textenum}
-
-The textenum environment is like the enumerate environment but is in-line. It
-uses the same counter that the enumerate environment would use at that level
-so the question can be compact but the answer can use enumerate instead. For
-
-
-example:
-
-
-
-
-\begin{onlyproblem}%
-
Differentiate the following:
-
\begin{textenum}
-
\item $f(x)=2^x$; \item $f(x)=\cot(x)$
-
\end{textenum}
-
\end{onlyproblem}
-
\begin{onlysolution}
-
\begin{enumerate}
-
\item
-
\begin{align*}
-
f(x) &= 2^x = \exp(\ln(x^2)) =\exp(2\ln(x))\\
-
f’(x) &= \exp(2\ln(x))\times \frac{2}{x}\\
-
&= f(x)\frac{2}{x}
-
\end{align*}
-
\item
-
\begin{align*}
-
f(x) &= \cot(x) = (\tan(x))^{-2}\\
-
f’(x) &= -(\tan(x))^{-2}\times\sec^2(x)\\
-
&=-\csc^2x
-
\end{align*}
-
\end{enumerate}
-
\end{onlysolution}
-
- In this example, the items in the question are brief, so an enumerate
-environment would result in a lot of unnecessary white space, but the answers
-require more space, so an enumerate environment is more appropriate. Since the
-textenum environment uses the same counters as the enumerate environment, the
-question and answer sheets use consistent labelling. Note that there are other
-packages available on CTAN that you can use to create in-line lists. Check the
-TeX Catalogue for further details.
-
\correctitem \incorrectitem
-
\correctitem
\incorrectitem
-
-You can use the commands \correctitem and \incorrectitem in place of
-\item. If the solutions are suppressed, these commands behave in the same way
-as \item, otherwise they format the item label using one of the commands:
-\correctitemformat \incorrectitemformat
-
\correctitemformat{⟨label⟩}
\incorrectitemformat{⟨label⟩}
-
-For example:
-
-
-
-
-Under which of the following functions does $S=\{a_1,a_2\}$
-
become a probability space?
-
\begin{enumerate}
-
\incorrectitem $P(a_1)=\frac{1}{3}$, $P(a_2)=\frac{1}{2}$
-
\correctitem $P(a_1)=\frac{3}{4}$, $P(a_2)=\frac{1}{4}$
-
\correctitem $P(a_1)=1$, $P(a_2)=0$
-
\incorrectitem $P(a_1)=\frac{5}{4}$, $P(a_2)=-\frac{1}{4}$
-
\end{enumerate}
-
- The default definition of \correctitemformat puts a frame around the
-label.
-

6 Defining a Problem
-It is possible to construct a problem sheet with solutions using the commands
-described in the previous sections, however it is also possible to define a set of
-problems for later use. In this way you can create an external file containing
-many problems some or all of which can be loaded and used in a document. The
-probsoln package has a default data set labelled “default” in which you can
-store problems. Alternatively, you can create multiple data sets. You
-can then iterate through each problem in a problem set. You can use a
-previously defined problem more than once, which means that by judicious
-use of onlyproblem, onlysolution or the showanswers boolean variable
-in conjunction with \showanswers and \hideanswers, you can print
-the solutions in a different location to the questions (for example in an
-appendix).
-
defproblem \begin{defproblem}[⟨n⟩][⟨default args⟩]{⟨label⟩}[⟨option⟩]⟨definition⟩\end{defproblem}
-
-This defines the problem whose label is given by ⟨label⟩. The label must be
-unique for a given data set and should not contain active characters or
-a comma. (Active characters include the special characters such as $
-and &, but some packages may make other symbols active, such as the
-colon (:) character. For example, the ngerman and babel packages make
-certain punctuation active. Check the relevant package documentation for
-details.)
-
-
-
The final optional argument
⟨option⟩ may be
fragile to indicate that the
-problem contains verbatim text. Any occurrences of
onlyproblem or
onlysolution
-contained within
defproblem are inherited from
defproblem. (See
§3 Verbatim for
-further details.)
-
-
If defproblem occurs in the document or is included via \input or \include,
-then the problem will be added to the default data set. If defproblem occurs in
-an external file that is loaded using one of the commands defined in §8 Loading
-Problems From External Files then the problem will be added to the specified
-data set.
-
The contents of the defproblem environment should be the text that defines
-the problem. This may include any of the commands defined in §4 Showing and
-Hiding Solutions and §5 General Formatting Commands.
-
The problem may optionally take ⟨n⟩ arguments (where ⟨n⟩ is from 0 to 9).
-The arguments can be referenced in the definition via #1,…,#9. If ⟨n⟩ is omitted
-then the problem doesn’t take any arguments. The following example defines a
-problem with one argument:
-
-
-
-
-\begin{defproblem}[1]{diffsin}
-
Differentiate $f(x)=\sin(#1x)$.
-
\begin{onlysolution}%
-
\begin{solution}
-
$f’(x) = #1\cos(#1x)$
-
\end{solution}
-
\end{onlysolution}
-
\end{defproblem}
-
-
-
The second optional argument ⟨default args⟩ supplies default problem
-arguments that will automatically be used within \thisproblem when used in
-\foreachproblem in conjunction with the package option usedefaultargs. (See §9
-Iterating Through Datasets.) For example:
-
-
-
-
-\begin{defproblem}[1][{2}]{diffsin}
-
Differentiate $f(x)=\sin(#1x)$.
-
\begin{onlysolution}%
-
\begin{solution}
-
$f’(x) = #1\cos(#1x)$
-
\end{solution}
-
\end{onlysolution}
-
\end{defproblem}
-
-
-
\newproblem \newproblem[⟨n⟩][⟨default args⟩]{⟨label⟩}{⟨problem⟩}{⟨solution⟩}
-
-
-This is a shortcut command for:
- \begin{defproblem}[⟨n⟩][⟨default args⟩]{⟨label⟩}%
-
⟨problem⟩%
-
\begin{onlysolution}%
-
\begin{solution}%
-
⟨solution⟩%
-
\end{solution}%
-
\end{onlysolution}%
-
\end{defproblem}
-
For example:
-
-
-
-
-\newproblem[1]{diffsin}{%
-
\(f(x) = \sin(#1x)\)
-
}%
-
{%
-
\(f’(x) = #1\cos(#1x)\)
-
}
-
- is equivalent to
-
-
-
-
-\begin{defproblem}[1]{diffcos}%
-
\(f(x) = \cos(#1x)\)
-
\begin{onlysolution}%
-
\begin{solution}%
-
\(f’(x) = -#1\sin(#1x)\)
-
\end{solution}%
-
\end{onlysolution}%
-
\end{defproblem}
-
- (In this example, the argument will need to be a positive number to avoid a
-double minus in the answer. If you want to perform floating point arithmetic on
-the arguments, then try the fp or pgfmath packages.)
-
Alternatively, if you want to supply default arguments to use when iterating
-through problems with \foreachproblem:
-
-
-
-
-\newproblem[1][{3}]{diffsin}{%
-
\(f(x) = \sin(#1x)\)
-
}%
-
{%
-
\(f’(x) = #1\cos(#1x)\)
-
}
-
-
-
\newproblem* \newproblem*[⟨n⟩][⟨default args⟩]{⟨label⟩}{⟨definition⟩}
-
-
-This is a shortcut for:
- \begin{defproblem}[⟨n⟩][⟨default args⟩]{⟨label⟩}%
-
⟨definition⟩%
-
\end{defproblem}
-
Note that you can’t use verbatim text with
\newproblem or
\newproblem*.
-Use the
defproblem environment instead with the
fragile option.
-
-
-
-Top
7 Using a Problem
-Once you have defined a problem using defproblem or \newproblem (see §6
-Defining a Problem), you can later display the problem using:
-
\useproblem \useproblem[⟨data set⟩]{⟨label⟩}{⟨arg1⟩}…{⟨argN⟩}
-
-
-where ⟨data set⟩ is the name of the data set that contains the problem (the
-default data set is used if omitted), ⟨label⟩ is the label identifying the required
-problem and ⟨arg1⟩, …, ⟨argN⟩ are the arguments to pass to the problem, if the
-problem was defined to have arguments (where N is the number of arguments
-specified when the problem was defined).
-
For example, in the previous section the problem diffcos was defined to have
-one argument, so it can be used as follows:
-
-
-
-
-\useproblem{diffcos}{3}
-
- This will be equivalent to:
-
-
-
-
-\(f(x) = \cos(3x)\)
-
\begin{onlysolution}%
-
\begin{solution}%
-
\(f’(x) = -3\sin(3x)\)
-
\end{solution}%
-
\end{onlysolution}%
-
-

8 Loading Problems From External Files
-You can store all your problem definitions (see §6 Defining a Problem) in an
-external file. These problems can all be appended to the default data set by
-including the file via \input or they can be appended to other data sets
-using one of the commands described below. Once you have loaded all
-the required problems, you can iterate through the data sets using the
-commands described in §9 Iterating Through Datasets. Note that the
-commands below will create a new data set, if the named data set doesn’t
-exist.
-
\loadallproblems \loadallproblems[⟨data set⟩]{⟨filename⟩}
-
-This will load all problems defined in ⟨filename⟩ and append them to the
-specified data set, in the order in which they are defined in the file. If ⟨data set⟩
-is omitted, the default data set will be used. If ⟨data set⟩ doesn’t exist, it will be
-created.
-
\loadselectedproblems \loadselectedproblems[⟨data set⟩]{⟨labels⟩}{⟨filename⟩}
-
-
-This is like \loadallproblems, but only those problems whose label is listed in
-the comma-separated list ⟨labels⟩ are loaded. For example, if I have some
-problems defined in the file derivatives.tex, then
-
-
-
-
-\loadselectedproblems{diffsin,diffcos}{derivatives}
-
- will only load the problems whose labels are diffsin and diffcos,
-respectively. All the other problems in the file will remain undefined.
-
\loadexceptproblems \loadexceptproblems[⟨data set⟩]{⟨exception
-
list⟩}{⟨filename⟩}
-
-This is the reverse of \loadselectedproblems. This loads all problems except
-those whose labels are listed in ⟨exception list⟩.
-
\loadrandomproblems \loadrandomproblems[⟨data set⟩]{⟨n⟩}{⟨filename⟩}
-
-
-This randomly loads ⟨n⟩ problems from ⟨filename⟩ and adds them to the given
-data set. If ⟨data set⟩ is omitted, the default data set is assumed. Note that the
-problems will be added to the data set in a random order, not in the order in
-which they were defined. There must be at least ⟨n⟩ problems defined in
-⟨filename⟩.
-
\loadrandomexcept \loadrandomexcept[⟨data set⟩]{⟨n⟩}{⟨filename⟩}{⟨exception
-
list⟩}
-
-This is similar to \loadrandomproblems except that it won’t load those
-problems whose labels are listed in ⟨exception list⟩. If you want to
-automatically exclude problems included in previous documents, see
-§8.1 Randomly Selecting Problems Not Selected in Previous
-Documents.
-
Note that the random number generator has been modified in version 3.01 in
-order to fix a bug. If you want to ensure that your random numbers are
-compatible with earlier versions, you can switch to the old generator
-using
-
\PSNuseoldrandom \PSNuseoldrandom
-
-
It is generally not a good idea to place anything in
⟨filename⟩ that is not
-inside the body of
defproblem or in the arguments to
\newproblem or
-
\newproblem*. All the commands in this section input the external file within a
-local scope, so command definitions would need to be made global to have any
-effect. In addition,
\loadrandomproblems has to load each file twice, which
-means that anything outside a problem definition will be parsed twice.
-
-
-

8.1 Randomly Selecting Problems Not Selected in Previous Documents
-Suppose you have a large set of questions that you want to randomly select for
-assignments and exams. The chances are, you don’t want to include questions
-that have been previously set for, say, the last three years. That is, you don’t
-want to select questions the students may already have seen. As from version
-3.03, you can now do this.
-
The probsoln package defaults to the UK academic year, which starts in
-September. If this isn’t appropriate, you can change it using:
-
\SetStartMonth \SetStartMonth{⟨n⟩}
-
-where ⟨n⟩ is the number of the month. (1 = January, 2 = February,
-etc.)
-
The start year is the calender year in effect when the academic
-year started. For example, if this is the academic year 2011/12, then
-the start year is 2011. This is automatically set to the start of the
-current academic year. It is also updated when \SetStartMonth is
-used.
-If you want to set it to a specific year, you can use:
-
\SetStartYear \SetStartYear{⟨year⟩}
-
-For example: \SetStartYear{2008} indicates the academic year 2008/9.
-
There are two files concerned with previously used labels. They are:
-
-
-The previously used labels file
- This keeps track of all problems used in
- previous years, as well as problems used by other documents that have
- this as their previously used labels file, and it contains the problem
- labels from the last run of the current document.
-
-
-The current used labels file
- This defaults to \jobname.prb, but the name can
- be changed using:
-
\SetUsedFileName \SetUsedFileName{⟨name⟩}
-
- This file keeps track of all the labels used in the current document from
- the previous LATEX run. Note that if you want to delete this file, first
- clear it using
-
-
-
\ClearUsedFile \ClearUsedFile{⟨file⟩}
-
- in place of \ExcludePreviousFile{⟨file⟩}, described below. The
- argument ⟨file⟩ is the previously used labels file described above.
- \ClearUsedFile will remove all labels in the current used labels file from
- the previously used labels file and clear the current used labels file. Once
- this file is empty, it may then be deleted.
-
-
- Before loading randomly selected problems, first specify the previously used
-labels file with the command:
-
\ExcludePreviousFile \ExcludePreviousFile[⟨number of years⟩]{⟨file
-
name⟩}
-
-where ⟨file name⟩ is the name of the previously used file. The optional argument
-⟨number of years⟩ specifies the year cut-off. This defaults to 3, which means that
-only those labels used this year or the previous 2 years will be kept. Any
-problems used before then may be reused.
-
Suppose I’m lecturing a first year undergraduate mathematics course
-(designated, say, mth101). I want to set assignments on each topic and an exam
-at the end of the year (as well as a resit or second sitting paper). I’ve got
-databases with problems for each topic, but the first and second sitting
-exams mustn’t include any of the problems used in the assignments
-or any problems used in assignments or exams for the previous two
-academic years. I’m going to arrange my directory structure as follows:
-
-
- - mth101/
-
- - assignment1/ (differentiation)
-
-
- - assignment2/ (probability spaces)
-
-
- - assignment3/ (linear algebra)
-
-
-
-
- - exams/
-
- - exam.tex (first sitting)
-
- - resit.tex (second sitting)
-
- - databases/
-
- - differentiation.tex
-
- - probabilityspaces.tex
-
- - linearalgebra.tex
-
- - previouslabels.tex (created by probsoln)

9 Iterating Through Datasets
-Once you have defined all your problems for a given data set, you can use an
-individual problem with \useproblem (see §7 Using a Problem) but it is more
-likely that you will want to iterate through all the problems so that
-you don’t need to remember the labels of all the problems you have
-defined.
-
\foreachproblem \foreachproblem[⟨data set⟩]{⟨body⟩}
-
-This does ⟨body⟩ for each problem in the given data set. If ⟨data set⟩ is omitted,
-the default data set is used. Within ⟨body⟩ you can use
-
\thisproblem \thisproblem
-
-to use the current problem and
-
\thisproblemlabel \thisproblemlabel
-
-to access the current label. If the problem requires arguments, and no default
-arguments were supplied in the problem definition or the package option
-usedefaultargs was not used, then you will be prompted for arguments, so if you
-
-
-want to use this approach you will need to use LATEX in interactive mode. If
-you do provide arguments, they will be stored in the event that you need to
-iterate through the data set again. The arguments will be included in
-\thisproblem, so you only need to use \thisproblem without having to specify
-\useproblem.
-
For example, to iterate through all problems in the default data set:
-
-
-
-
-\begin{enumerate}
-
\foreachproblem{\item\thisproblem}
-
\end{enumerate}
-
-
-
\foreachsolution \foreachsolution[⟨data set⟩]{⟨body⟩}
-
-This is equivalent to \foreachsolution, but only iterates through problems
-that contain the onlysolution environment. Note that you still need to use
-\showanswers or the answers package option for the contents of the onlysolution
-environment to appear.
-
\foreachdataset \foreachdataset{⟨cmd⟩}{⟨body⟩}
-
-This does ⟨body⟩ for each of the defined data sets. Within ⟨body⟩, ⟨cmd⟩ will be
-set to the name of the current data set. For example, to display all problems in
-all data sets:
-
-
-
-
-\begin{enumerate}
-
\foreachdataset{\thisdataset}{%
-
\foreachproblem[\thisdataset]{\item\thisproblem}}
-
\end{enumerate}
-
-
-
Suppose I have two external files called derivatives.tex and
-probspaces.tex which define problems using both onlyproblem and onlysolution
-for example:
-
-
-
-
-\begin{defproblem}{cosxsqsinx}%
-
\begin{onlyproblem}%
-
$y = \cos(x^2)\sin x$.%
-
\end{onlyproblem}%
-
\begin{onlysolution}%
-
\[\frac{dy}{dx} = -\sin(x^2)2x\sin x + \cos(x^2)\cos x\]
-
\end{onlysolution}%
-
\end{defproblem}
-
- I can write a document that creates two data sets, one for the derivative
-problems and one for the problems about probability spaces. I can then use
-\hideanswers and iterate through the require data set to produce the
-problems. Later, I can use \showanswers and iterate over all problems defined
-in both data sets to produce the chapter containing all the answers. When
-displaying the questions, I have taken advantage of the fact that I can
-cross-reference items within an enumerate environment, and redefined
-\theenumi to label the questions according to the chapter. The cross-reference
-label is constructed from the problem label and is referenced in the
-answer section to ensure that the answers have the same label as the
-questions.

10 Random Number Generator
-This package provides a pseudo-random number generator that is used by
-\loadrandomproblems. As noted earlier the random number generator has been
-modified in version 3.01 in order to fix a bug. If you want to ensure that your
-random numbers are compatible with earlier versions, you can switch to the old
-generator using
-
\PSNuseoldrandom \PSNuseoldrandom
-
-
\PSNrandseed \PSNrandseed{⟨n⟩}
-
-This sets the seed to ⟨n⟩ which must be a non-zero integer. For example, to
-generate a different set of random numbers every time you LATEX your
-document,
-put the following in your preamble:
-
-
-
-
-\PSNrandseed{\time}
-
- or to generate a different set of random numbers every year you LATEX your
-document:
-
-
-
-
-\PSNrandseed{\year}
-
-
-
\PSNgetrandseed \PSNgetrandseed{⟨register⟩}
-
-This stores the current seed in the count register specified by ⟨register⟩. For
-example:
-
-
-
-
-\newcount\myseed
-
\PSNgetrandseed{\myseed}
-
-
-
\PSNrandom \PSNrandom{⟨register⟩}{⟨n⟩}
-
-Generates a random integer from 1 to ⟨n⟩ and stores in the count register
-specified by ⟨register⟩. For example, the following generates an integer from 1 to
-10 and stores it in the register \myreg:
-
-
-
-
-\newcount\myreg
-
\PSNrandom{\myreg}{10}
-
-
-
\random \random{⟨counter⟩}{⟨min⟩}{⟨max⟩}
-
-Generates a random integer from ⟨min⟩ to ⟨max⟩ and stores in the given
-counter. For example, the following generates a random number between 3 and
-8 (inclusive) and stores it in the counter myrand.
-
-
-
-
-\newcounter{myrand}
-
\random{myrand}{3}{8}
-
-
-
\doforrandN \doforrandN{⟨n⟩}{⟨cmd⟩}{⟨list⟩}{⟨text⟩}
-
-Randomly selects ⟨n⟩ values from the comma-separated list given by
-⟨list⟩ and iterates through this subset. On each iteration it sets ⟨cmd⟩
-to the current value and does ⟨text⟩. For example, the following will
-load a randomly selected problem from two of the listed files (where
-file1.tex, file2.tex and file3.tex are files containing at least one
-problem):
-
-
-
-
-\doforrandN{2}{\thisfile}{file1,file2,file3}{%
-
\loadrandomproblems{1}{\thisfile}}
-

11 Compatibility With Versions Prior to 3.0
-Version 3.0 of the probsoln package completely changed the structure of the
-package, but the commands described in this section have been provided to
-maintain compatibility with earlier versions. The only problems that are likely
-to occur are those where commands are contained within groups. This will effect
-any commands that are contained in external files that are outside of the
-arguments to \newproblem and \newproblem*. However, since the external files
-had to be parsed twice in order to load the problems, this shouldn’t be an issue
-as adding anything other than problem definitions in those files would be
-problematic anyway.
-
The other likely difference is where the random generator is used in a group.
-This includes commands such as \selectrandomly. For example, if your
-document contained something like:
-
-
-
-
-\begin{enumerate}
-
\selectrandomly{file1}{8}
-
\item Solve the following:
-
\begin{enumerate}
-
\selectrandomly{file2}{4}
-
\end{enumerate}
-
\selectrandomly{file3}{2}
-
\end{enumerate}
-
- Then using versions prior to v3.0 will produce a different set of random
-numbers since the second \selectrandomly is in a different level of grouping. If
-you want to ensure that the document produces exactly the same random set
-with the new version as with the old version, you will need to get and set the
-random number seed. For example, the above would need to be modified so that
-it becomes:
-
-
-
-
-\begin{enumerate}
-
\selectrandomly{file1}{8}
-
\item Solve the following:
-
\newcount\oldseed
-
\PSNgetrandseed{\oldseed}
-
\begin{enumerate}
-
\selectrandomly{file2}{4}
-
\end{enumerate}
-
\PSNrandseed{\oldseed}
-
\selectrandomly{file3}{2}
-
\end{enumerate}
-
-
-
\selectrandomly \selectrandomly{⟨filename⟩}{⟨n⟩}
-
-This is now equivalent to:
- {\loadrandomproblems[⟨filename⟩]{⟨n⟩}{⟨filename⟩}}%
-
\foreachproblem[⟨filename⟩]{\PSNitem\thisproblem\endPSNitem}
-
\selectallproblems \selectallproblems{⟨filename⟩}
-
-This is now equivalent to:
- {\loadallproblems[⟨filename⟩]{⟨filename⟩}}%
-
\foreachproblem[⟨filename⟩]{\PSNitem\thisproblem\endPSNitem}
-
Note that in both the above cases, a new data set is created with the same
-name as the file name.

- \section{Introduction}
-The \styfmt{probsoln} package is designed for teachers or lecturers
-who want to create problem sheets for their students. This package
-was designed with mathematics problems in mind, but can be used for
-other subjects as well. The idea is to create a file containing a
-large number of problems with their solutions which can be read in
-by \LaTeX, and then select a number of problems to typeset. This
-means that once the database has been set up, each year you can
-easily create a new problem sheet that is sufficiently different
-from the previous year, thus preventing the temptation of current
-students seeking out the previous year's students, and checking out
-their answers. There is also an option that can be passed to the
-package to determine whether or not the solutions should be printed.
-In this way, one file can either produce the student's version or
-the teacher's version.
-
-\section{Package Options}\label{sec:pkgopt}
-The following options may be passed to this package:
-\begin{description}
-\item[\pkgopt{answers}] Show the answers
-\item[\pkgopt{noanswers}] Don't show the answers (default)
-\item[\pkgopt{draft}] Display the label and dataset name when a problem is used
-\item[\pkgopt{final}] Don't display label and dataset name when a problem is used
-\item[\pkgopt{usedefaultargs}] Make \ics{thisproblem} use the
-default arguments supplied in the problem definition.
-\item[\pkgopt{nousedefaultargs}] Make \ics{thisproblem} prompt for
-problem arguments (default).
-\end{description}
-
-\section{Verbatim}\label{sec:verbatim}
-
-As from version 3.02, problems and solutions may contain verbatim
-text, but you must use the \iterm{fragile}\texttt{fragile} (or
-\texttt{fragile=true}) option for the associated environments.
-
-Alternatively, if most of your problems contain verbatim, you can
-globally set this option using:
-\begin{verbatim}
-\setkeys{probsoln}{fragile}
-\end{verbatim}
-You can switch off this option using \texttt{fragile=false}.
-
-The \texttt{fragile} option writes information to a temporary file.
-This defaults to "\jobname.vrb" but the name may be changed. The
-extension (".vrb") is given by:
-\begin{definition}[\DescribeMacro{\ProbSolnFragileExt}]
-\cs{ProbSolnFragileExt}
-\end{definition}
-The base name (\cs{jobname}) is given by:
-\begin{definition}[\DescribeMacro{\ProbSolnFragileFile}]
-\cs{ProbSolnFragileFile}
-\end{definition}
-
-\section{Showing and Hiding Solutions}\label{sec:showanswers}
-
-In addition to the \pkgopt{answers} and \pkgopt{noanswers} package
-options, it is also possible to show or suppress the solutions
-using
-\begin{definition}[\DescribeMacro{\showanswers}]
-\cs{showanswers}
-\end{definition}
-and
-\begin{definition}[\DescribeMacro{\hideanswers}]
-\cs{hideanswers}
-\end{definition}
-respectively.
-
-The boolean variable \bool{showanswers} determines whether the
-answers should be displayed. You can use this value with the
-\sty{ifthen} package to specify different text depending on
-whether the solutions should be displayed. For example:
-\begin{verbatim}
-Assignment 1\ifthenelse{\boolean{showanswers}}{ (Solution Sheet)}{}
-\end{verbatim}
-Alternatively you can use \ics{ifshowanswers}\ldots\cs{else}\ldots
-\cs{fi}:
-\begin{verbatim}
-Assignment 1\ifshowanswers\space (Solution Sheet)\fi
-\end{verbatim}
-
-For longer passages, you can use the environments
-\begin{definition}[\DescribeEnv{onlyproblem}]
-\cs{begin}\marg{onlyproblem}\oarg{option}
-\end{definition}
-and
-\begin{definition}[\DescribeEnv{onlysolution}]
-\cs{begin}\marg{onlysolution}\oarg{option}
-\end{definition}
-For example:
-\begin{verbatim}
-\begin{onlyproblem}%
-What is the derivative of $f(x) = x^2$?
-\end{onlyproblem}%
-\begin{onlysolution}%
-$f'(x) = 2x$
-\end{onlysolution}
-\end{verbatim}
-The above will only display the question if \bool{showanswers}
-is false and will only display the solution if \bool{showanswers}
-is true. If you want the question to appear in the answer
-sheet as well as the solution, then don't put the question in
-the \env{onlyproblem} environment:
-\begin{verbatim}
-What is the derivative of $f(x) = x^2$?
-\begin{onlysolution}%
-Solution: $f'(x) = 2x$
-\end{onlysolution}
-\end{verbatim}
-
-\begin{important}
-If you want to include verbatim text in the body of
-\env{onlyproblem} or \env{onlysolution}, you need to specify
-\texttt{fragile} in the optional argument of the environment.
-(See \sectionref{sec:verbatim} for further details.)
-\end{important}
-
-If you use \envfmt{onlysolution} within the \env{defproblem}
-environment, the problem will be tagged as having a solution
-and will be added to the list used by \ics{foreachsolution}.
-The optional argument of \envfmt{onlysolution} (and \env{onlyproblem})
-is inherited from the parent \env{defproblem} setting.
-
-\section{General Formatting Commands}\label{sec:formatting}
-
-The commands and environments described in this section are
-provided to assist formatting problems and their solutions.
-\begin{definition}[\DescribeEnv{solution}]
-\verb|\begin{solution}|\meta{text}\verb|\end{solution}|
-\end{definition}
-By default, this is equivalent to
-\begin{display}
-\verb|\par\noindent\textbf{\solutionname}: |\meta{text}
-\end{display}
-where \DescribeMacro{\solutionname}\cs{solutionname} defaults
-to \dq{\solutionname}. Note that you must place the \env{solution}
-environment inside the \envfmt{onlysolution} environment or
-between \ics{ifshowanswers}\ldots\cs{fi} to ensure that it
-is suppressed when the solutions are not wanted. (See
-\sectionref{sec:showanswers}.)
-
-
-Note that the \styfmt{probsoln} package will only define the
-\env{solution} environment if it is not already defined.
-
-\begin{definition}[\DescribeEnv{textenum}]
-\verb|\begin{textenum}|\ldots\verb|\end{textenum}|
-\end{definition}
-The \envfmt{textenum} environment is like the \env{enumerate}
-environment but is in-line. It uses the same counter that the
-\envfmt{enumerate} environment would use at that level so the
-question can be compact but the answer can use \envfmt{enumerate}
-instead. For example:
-\begin{verbatim}
-\begin{onlyproblem}%
- Differentiate the following:
- \begin{textenum}
- \item $f(x)=2^x$; \item $f(x)=\cot(x)$
- \end{textenum}
-\end{onlyproblem}
-\begin{onlysolution}
- \begin{enumerate}
- \item
- \begin{align*}
- f(x) &= 2^x = \exp(\ln(x^2)) =\exp(2\ln(x))\\
- f'(x) &= \exp(2\ln(x))\times \frac{2}{x}\\
- &= f(x)\frac{2}{x}
- \end{align*}
- \item
- \begin{align*}
- f(x) &= \cot(x) = (\tan(x))^{-2}\\
- f'(x) &= -(\tan(x))^{-2}\times\sec^2(x)\\
- &=-\csc^2x
- \end{align*}
- \end{enumerate}
-\end{onlysolution}
-\end{verbatim}
-In this example, the items in the question are brief, so an
-\env{enumerate} environment would result in a lot of unnecessary
-white space, but the answers require more space, so an
-\envfmt{enumerate} environment is more appropriate. Since the
-\envfmt{textenum} environment uses the same counters as the
-\envfmt{enumerate} environment, the question and answer sheets use
-consistent labelling. Note that there are other packages available
-on CTAN that you can use to create in-line lists. Check the
-\urlfootref{http://www.tex.ac.uk/tex-archive/help/Catalogue/bytopic.html\#enumeration}{TeX
-Catalogue} for further details.
-
-\DescribeMacro{\correctitem}\DescribeMacro{\incorrectitem}
-\begin{definition}
-\cs{correctitem}\\
-\cs{incorrectitem}
-\end{definition}
-You can use the commands \cs{correctitem} and \cs{incorrectitem}
-in place of \ics{item}. If the solutions are suppressed, these
-commands behave in the same way as \cs{item}, otherwise they
-format the item label using one of the commands:
-\DescribeMacro{\correctitemformat}\DescribeMacro{\incorrectitemformat}
-\begin{definition}
-\cs{correctitemformat}\marg{label}\\
-\cs{incorrectitemformat}\marg{label}
-\end{definition}
-For example:
-\begin{verbatim}
-Under which of the following functions does $S=\{a_1,a_2\}$
-become a probability space?
-\begin{enumerate}
-\incorrectitem $P(a_1)=\frac{1}{3}$, $P(a_2)=\frac{1}{2}$
-\correctitem $P(a_1)=\frac{3}{4}$, $P(a_2)=\frac{1}{4}$
-\correctitem $P(a_1)=1$, $P(a_2)=0$
-\incorrectitem $P(a_1)=\frac{5}{4}$, $P(a_2)=-\frac{1}{4}$
-\end{enumerate}
-\end{verbatim}
-The default definition of \cs{correctitemformat} puts a frame around
-the label.
-
-\section{Defining a Problem}\label{sec:defproblem}
-
-It is possible to construct a problem sheet with solutions using the
-commands described in the previous sections, however it is also
-possible to define a set of problems for later use. In this way you
-can create an external file containing many problems some or all of
-which can be loaded and used in a document. The \styfmt{probsoln}
-package has a default data set labelled \dq{default} in which you
-can store problems. Alternatively, you can create multiple data
-sets. You can then iterate through each problem in a problem set.
-You can use a previously defined problem more than once, which means
-that by judicious use of \env{onlyproblem}, \env{onlysolution} or
-the \bool{showanswers} boolean variable in conjunction with
-\ics{showanswers} and \ics{hideanswers}, you can print the solutions
-in a different location to the questions (for example in an
-appendix).
-
-\begin{definition}[\DescribeEnv{defproblem}]
-\verb|\begin{defproblem}|\oarg{n}\oarg{default args}\marg{label}\oarg{option}\newline
-\meta{definition}\newline
-\verb|\end{defproblem}|
-\end{definition}
-This defines the problem whose label is given by \meta{label}. The
-label must be unique for a given data set and should not contain
-active characters or a comma. (Active characters include the special characters
-such as \$ and \&, but some packages may make other symbols active,
-such as the colon (:) character. For example, the \sty{ngerman} and
-\sty{babel} packages make certain punctuation active. Check the
-relevant package documentation for details.)
-
-\begin{important}
-The final optional argument \meta{option} may be \texttt{fragile} to
-indicate that the problem contains verbatim text. Any occurrences of
-\env{onlyproblem} or \env{onlysolution} contained within
-\envfmt{defproblem} are inherited from \envfmt{defproblem}. (See
-\sectionref{sec:verbatim} for further details.)
-\end{important}
-
-If \env{defproblem} occurs in the document or is included via
-\ics{input} or \ics{include}, then the problem will be added to
-the default data set. If \envfmt{defproblem} occurs in an external
-file that is loaded using one of the commands defined in
-\sectionref{sec:load} then the problem will be added to
-the specified data set.
-
-The contents of the \env{defproblem} environment should be the text
-that defines the problem. This may include any of the commands
-defined in \sectionref{sec:showanswers} and
-\sectionref{sec:formatting}.
-
-The problem may optionally take \meta{n} arguments (where
-\meta{n} is from 0 to 9). The arguments can be referenced
-in the definition via \texttt{\#1},\ldots,\texttt{\#9}.
-If \meta{n} is omitted then the problem doesn't take any
-arguments.
-The following example defines a problem with one argument:
-\begin{verbatim}
-\begin{defproblem}[1]{diffsin}
-Differentiate $f(x)=\sin(#1x)$.
-\begin{onlysolution}%
- \begin{solution}
- $f'(x) = #1\cos(#1x)$
- \end{solution}
-\end{onlysolution}
-\end{defproblem}
-\end{verbatim}
-
-The second optional argument \meta{default args} supplies
-default problem arguments that will automatically be used within
-\ics{thisproblem} when used in \ics{foreachproblem} in conjunction
-with the package option \pkgopt{usedefaultargs}. (See \sectionref{sec:foreach}.)
-For example:
-\begin{verbatim}
-\begin{defproblem}[1][{2}]{diffsin}
-Differentiate $f(x)=\sin(#1x)$.
-\begin{onlysolution}%
- \begin{solution}
- $f'(x) = #1\cos(#1x)$
- \end{solution}
-\end{onlysolution}
-\end{defproblem}
-\end{verbatim}
-
-\begin{definition}[\DescribeMacro{\newproblem}]
-\cs{newproblem}\oarg{n}\oarg{default args}\marg{label}\marg{problem}\marg{solution}
-\end{definition}
-This is a shortcut command for:
-\begin{ttfamily}\obeylines
-\cs{begin}\{defproblem\}\oarg{n}\oarg{default args}\marg{label}\%
-\meta{problem}\%
-\cs{begin}\{onlysolution\}\%
-\cs{begin}\{solution\}\%
-\meta{solution}\%
-\cs{end}\{solution\}\%
-\cs{end}\{onlysolution\}\%
-\cs{end}\{defproblem\}
-\end{ttfamily}
-For example:
-\begin{verbatim}
-\newproblem[1]{diffsin}{%
- \(f(x) = \sin(#1x)\)
-}%
-{%
- \(f'(x) = #1\cos(#1x)\)
-}
-\end{verbatim}
-is equivalent to
-\begin{verbatim}
-\begin{defproblem}[1]{diffcos}%
- \(f(x) = \cos(#1x)\)
-\begin{onlysolution}%
- \begin{solution}%
- \(f'(x) = -#1\sin(#1x)\)
- \end{solution}%
-\end{onlysolution}%
-\end{defproblem}
-\end{verbatim}
-(In this example, the argument will need to be a positive number
-to avoid a double minus in the answer. If you want to perform
-floating point arithmetic on the arguments, then try the
-\sty{fp} or \sty{pgfmath} packages.)
-
-Alternatively, if you want to supply default arguments to use when
-iterating through problems with \ics{foreachproblem}:
-\begin{verbatim}
-\newproblem[1][{3}]{diffsin}{%
- \(f(x) = \sin(#1x)\)
-}%
-{%
- \(f'(x) = #1\cos(#1x)\)
-}
-\end{verbatim}
-
-
-\begin{definition}[\DescribeMacro{\newproblem*}]
-\cs{newproblem*}\oarg{n}\oarg{default args}\marg{label}\marg{definition}
-\end{definition}
-This is a shortcut for:
-\begin{ttfamily}\obeylines
-\cs{begin}\{defproblem\}\oarg{n}\oarg{default args}\marg{label}\%
-\meta{definition}\%
-\cs{end}\{defproblem\}
-\end{ttfamily}
-
-\begin{important}
-Note that you can't use verbatim text with \cs{newproblem} or
-\cs{newproblem*}. Use the \env{defproblem} environment instead with
-the \texttt{fragile option}.
-\end{important}
-
-\section{Using a Problem}\label{sec:useproblem}
-
-Once you have defined a problem using \env{defproblem} or
-\ics{newproblem} (see \sectionref{sec:defproblem}), you can
-later display the problem using:
-\begin{definition}[\DescribeMacro{\useproblem}]
-\cs{useproblem}\oarg{data set}\marg{label}\marg{arg$_1$}\ldots
-\marg{arg$_N$}
-\end{definition}
-where \meta{data set} is the name of the data set that contains
-the problem (the default data set is used if omitted),
-\meta{label} is the label identifying the required problem and
-\meta{arg$_1$}, \ldots, \meta{arg$_N$}
-are the arguments to pass to the problem, if the problem was
-defined to have arguments (where $N$ is the number
-of arguments specified when the problem was defined).
-
-For example, in the previous section the problem \texttt{diffcos}
-was defined to have one argument, so it can be used as follows:
-\begin{verbatim}
-\useproblem{diffcos}{3}
-\end{verbatim}
-This will be equivalent to:
-\begin{verbatim}
-\(f(x) = \cos(3x)\)
-\begin{onlysolution}%
-\begin{solution}%
-\(f'(x) = -3\sin(3x)\)
-\end{solution}%
-\end{onlysolution}%
-\end{verbatim}
-
-\section{Loading Problems From External Files}\label{sec:load}
-
-You can store all your problem definitions (see
-\sectionref{sec:defproblem}) in an external file.
-These problems can all be appended to the default data set by
-including the file via \ics{input} or they can be appended
-to other data sets using one of the commands described below.
-Once you have loaded all the required problems, you can
-iterate through the data sets using the commands described
-in \sectionref{sec:foreach}. Note that the commands below
-will create a new data set, if the named data set doesn't
-exist.
-
-\begin{definition}[\DescribeMacro{\loadallproblems}]
-\cs{loadallproblems}\oarg{data set}\marg{filename}
-\end{definition}
-This will load all problems defined in \meta{filename} and
-append them to the specified data set, in the order in which
-they are defined in the file. If \meta{data set} is
-omitted, the default data set will be used. If \meta{data set}
-doesn't exist, it will be created.
-
-\begin{definition}[\DescribeMacro{\loadselectedproblems}]
-\cs{loadselectedproblems}\oarg{data set}\marg{labels}\marg{filename}
-\end{definition}
-This is like \cs{loadallproblems}, but only those problems whose
-label is listed in the comma-separated list \meta{labels} are
-loaded. For example, if I have some problems defined in the
-file \texttt{derivatives.tex}, then
-\begin{verbatim}
-\loadselectedproblems{diffsin,diffcos}{derivatives}
-\end{verbatim}
-will only load the problems whose labels are \texttt{diffsin}
-and \texttt{diffcos}, respectively. All the other problems in
-the file will remain undefined.
-
-\begin{definition}[\DescribeMacro{\loadexceptproblems}]
-\cs{loadexceptproblems}\oarg{data set}\marg{exception list}\marg{filename}
-\end{definition}
-This is the reverse of \cs{loadselectedproblems}. This loads all
-problems except those whose labels are listed in \meta{exception
-list}.
-
-\begin{definition}[\DescribeMacro{\loadrandomproblems}]
-\cs{loadrandomproblems}\oarg{data set}\marg{n}\marg{filename}
-\end{definition}
-This randomly loads \meta{n} problems from \meta{filename} and
-adds them to the given data set. If \meta{data set} is omitted,
-the default data set is assumed. Note that the problems will be
-added to the data set in a random order, not in the order in
-which they were defined. There must be at least \meta{n} problems
-defined in \meta{filename}.
-
-\begin{definition}[\DescribeMacro{\loadrandomexcept}]
-\cs{loadrandomexcept}\oarg{data
-set}\marg{n}\marg{filename}\marg{exception list}
-\end{definition}
-This is similar to \cs{loadrandomproblems} except that it won't load
-those problems whose labels are listed in \meta{exception list}.
-\textbf{If you want to automatically exclude problems included in
-previous documents, see \sectionref{sec:exprev}.}
-
-Note that the random number generator has been modified in version
-3.01 in order to fix a bug. If you want to ensure that your random
-numbers are compatible with earlier versions, you can switch to the
-old generator using
-\begin{definition}[\DescribeMacro{\PSNuseoldrandom}]
-\cs{PSNuseoldrandom}
-\end{definition}
-
-\begin{important}
-It is generally not a good idea to place anything in
-\meta{filename} that is not inside the body of \env{defproblem}
-or in the arguments to \ics{newproblem} or \ics{newproblem*}.
-All the commands in this section input the external file within
-a local scope, so command definitions would need to be made
-global to have any effect. In addition, \cs{loadrandomproblems}
-has to load each file twice, which means that anything outside
-a problem definition will be parsed twice.
-\end{important}
-
-\subsection{Randomly Selecting Problems Not Selected in Previous
-Documents}
-\label{sec:exprev}
-
-Suppose you have a large set of questions that you want to randomly
-select for assignments and exams. The chances are, you don't want to
-include questions that have been previously set for, say, the last
-three years. That is, you don't want to select questions the
-students may already have seen. As from version 3.03, you can now do
-this.
-
-The \sty{probsoln} package defaults to the UK academic year, which
-starts in September. If this isn't appropriate, you can change it
-using:
-\begin{definition}[\DescribeMacro{\SetStartMonth}]
-\cs{SetStartMonth}\marg{n}
-\end{definition}
-where \meta{n} is the number of the month. (1 = January, 2 =
-February, etc.)
-
-The \emph{start year} is the calender year in effect when the
-academic year started. For example, if this is the academic year
-2011/12, then the start year is 2011. This is automatically set to
-the start of the current academic year. It is also updated when
-\cs{SetStartMonth} is used.\footnote{So don't use \cs{SetStartMonth}
-after \cs{SetStartYear}.} If you want to set it to a specific year,
-you can use:
-\begin{definition}[\DescribeMacro{\SetStartYear}]
-\cs{SetStartYear}\marg{year}
-\end{definition}
-For example: \verb|\SetStartYear{2008}| indicates the academic year
-2008/9.
-
-There are two files concerned with previously used labels. They are:
-\begin{description}
-
- \item[The previously used labels file] This keeps track of all
- problems used in previous years, as well as problems used by
- other documents that have this as their previously used labels
- file, and it contains the problem labels from the last run of
- the current document.
-
- \item[The current used labels file] This defaults to
-\cs{jobname}\texttt{.prb}, but the name can be changed using:
- \begin{definition}[\DescribeMacro{\SetUsedFileName}]
- \cs{SetUsedFileName}\marg{name}
- \end{definition}
- This file keeps track of all the labels used in the current
- document from the previous \LaTeX\ run. Note that if you want to
- delete this file, first clear it using
- \begin{definition}[\DescribeMacro{\ClearUsedFile}]
- \cs{ClearUsedFile}\marg{file}
- \end{definition}
- in place of \cs{ExcludePreviousFile}\marg{file}, described below.
- The argument \meta{file} is the previously used labels file
- described above. \cs{ClearUsedFile} will remove all labels in
- the current used labels file from the previously used labels file
- and clear the current used labels file. Once this file is empty,
- it may then be deleted.
-
-\end{description}
-
-Before loading randomly selected problems, first specify the
-previously used labels file with the command:
-\begin{definition}[\DescribeMacro{\ExcludePreviousFile}]
-\cs{ExcludePreviousFile}\oarg{number of years}\marg{file name}
-\end{definition}
-where \meta{file name} is the name of the previously used file. The
-optional argument \meta{number of years} specifies the year cut-off.
-This defaults to 3, which means that only those labels used this
-year or the previous 2 years will be kept. Any problems used before
-then may be reused.
-
-Suppose I'm lecturing a first year undergraduate mathematics course
-(designated, say, mth101). I want to set assignments on each topic
-and an exam at the end of the year (as well as a resit or second
-sitting paper). I've got databases with problems for each topic, but
-the first and second sitting exams mustn't include any of the
-problems used in the assignments or any problems used in assignments
-or exams for the previous two academic years. I'm going to arrange
-my directory structure as follows:
-\begin{itemize}
-\item \texttt{mth101/}
- \begin{itemize}
- \item \texttt{assignment1/} (differentiation)
- \begin{itemize}
- \item \texttt{assignment1.tex}
- \end{itemize}
- \item \texttt{assignment2/} (probability spaces)
- \begin{itemize}
- \item \texttt{assignment2.tex}
- \end{itemize}
- \item \texttt{assignment3/} (linear algebra)
- \begin{itemize}
- \item \texttt{assignment3.tex}
- \end{itemize}
- \item \texttt{exams/}
- \begin{itemize}
- \item \texttt{exam.tex} (first sitting)
- \item \texttt{resit.tex} (second sitting)
- \end{itemize}
- \item \texttt{databases/}
- \begin{itemize}
- \item \texttt{differentiation.tex}
- \item \texttt{probabilityspaces.tex}
- \item \texttt{linearalgebra.tex}
- \end{itemize}
- \item \texttt{previouslabels.tex} (created by \sty{probsoln})
- \end{itemize}
-\end{itemize}
-
-\section{Iterating Through Datasets}\label{sec:foreach}
-
-Once you have defined all your problems for a given data set, you
-can use an individual problem with \ics{useproblem} (see
-\sectionref{sec:useproblem}) but it is more likely that you will
-want to iterate through all the problems so that you don't need to
-remember the labels of all the problems you have defined.
-
-\begin{definition}[\DescribeMacro{\foreachproblem}]
-\cs{foreachproblem}\oarg{data set}\marg{body}
-\end{definition}
-This does \meta{body} for each problem in the given data set.
-If \meta{data set} is omitted, the default data set is used.
-Within \meta{body} you can use
-\begin{definition}[\DescribeMacro{\thisproblem}]
-\cs{thisproblem}
-\end{definition}
-to use the current problem and
-\begin{definition}[\DescribeMacro{\thisproblemlabel}]
-\cs{thisproblemlabel}
-\end{definition}
-to access the current label. If the problem requires arguments,
-and no default arguments were supplied in the problem definition or
-the package option \pkgopt{usedefaultargs} was not used, then
-you will be prompted for arguments, so if you want to use this
-approach you will need to use \LaTeX\ in interactive mode. If
-you do provide arguments, they will be stored in the event that
-you need to iterate through the data set again. The
-arguments will be included in \cs{thisproblem}, so you only
-need to use \cs{thisproblem} without having to specify
-\ics{useproblem}.
-
-For example, to iterate through all problems
-in the default data set:
-\begin{verbatim}
-\begin{enumerate}
-\foreachproblem{\item\thisproblem}
-\end{enumerate}
-\end{verbatim}
-
-\begin{definition}[\DescribeMacro{\foreachsolution}]
-\cs{foreachsolution}\oarg{data set}\marg{body}
-\end{definition}
-This is equivalent to \cs{foreachsolution}, but only iterates
-through problems that contain the \env{onlysolution} environment.
-Note that you still need to use \ics{showanswers} or the
-\pkgopt{answers} package option for the contents of the
-\env{onlysolution} environment to appear.
-
-\begin{definition}[\DescribeMacro{\foreachdataset}]
-\cs{foreachdataset}\marg{cmd}\marg{body}
-\end{definition}
-This does \meta{body} for each of the defined data sets. Within
-\meta{body}, \meta{cmd} will be set to the name of the current
-data set. For example, to display all problems in all data sets:
-\begin{verbatim}
-\begin{enumerate}
-\foreachdataset{\thisdataset}{%
-\foreachproblem[\thisdataset]{\item\thisproblem}}
-\end{enumerate}
-\end{verbatim}
-
-Suppose I have two external files called
-\texttt{derivatives.tex} and \texttt{probspaces.tex} which
-define problems using both \env{onlyproblem} and
-\env{onlysolution} for example:
-\begin{verbatim}
-\begin{defproblem}{cosxsqsinx}%
-\begin{onlyproblem}%
-$y = \cos(x^2)\sin x$.%
-\end{onlyproblem}%
-\begin{onlysolution}%
-\[\frac{dy}{dx} = -\sin(x^2)2x\sin x + \cos(x^2)\cos x\]
-\end{onlysolution}%
-\end{defproblem}
-\end{verbatim}
-I can write a document that creates two data sets, one for
-the derivative problems and one for the problems about
-probability spaces. I can then use \ics{hideanswers} and
-iterate through the require data set to produce the problems.
-Later, I can use \ics{showanswers} and iterate over all problems defined in both data
-sets to produce the chapter containing all the answers. When
-displaying the questions, I have taken advantage of the fact that
-I can cross-reference items within an \env{enumerate} environment,
-and redefined \ics{theenumi} to label the questions according to
-the chapter. The cross-reference label is constructed from
-the problem label and is referenced in the answer section to
-ensure that the answers have the same label as the questions.
-\begin{verbatim}
-\documentclass{report}
-\usepackage{probsoln}
-\begin{document}
-\hideanswers
-\chapter{Differentiation}
-% randomly select 25 problems from derivatives.tex and add to
-% the data set called 'deriv'
-\loadrandomproblems[deriv]{25}{derivatives}
-
-% Display the problems
-\renewcommand{\theenumi}{\thechapter.\arabic{enumi}}
-\begin{enumerate}
-\foreachproblem[deriv]{\item\label{prob:\thisproblemlabel}\thisproblem}
-\end{enumerate}
-% You may need to change \theenumi back here
-
-\chapter{Probability Spaces}
-% randomly select 25 problems from probspaces.tex and add to
-% the data set called 'spaces'
-\loadrandomproblems[spaces]{25}{probspaces}
-
-% Display the problems
-\renewcommand{\theenumi}{\thechapter.\arabic{enumi}}
-\begin{enumerate}
-\foreachproblem[spaces]{\item\label{prob:\thisproblemlabel}\thisproblem}
-\end{enumerate}
-% You may need to change \theenumi back here
-
-\appendix
-
-\chapter{Solutions}
-\showanswers
-\begin{itemize}
-\foreachdataset{\thisdataset}{%
-\foreachproblem[\thisdataset]{\item[\ref{prob:\thisproblemlabel}]\thisproblem}
-}
-\end{itemize}
-
-\end{document}
-\end{verbatim}
-
-\section{Random Number Generator}\label{sec:random}
-
-This package provides a pseudo-random number generator that is used
-by \ics{loadrandomproblems}. As noted earlier the random number
-generator has been modified in version 3.01 in order to fix a bug.
-If you want to ensure that your random numbers are compatible with
-earlier versions, you can switch to the old generator using
-\begin{definition}[\DescribeMacro{\PSNuseoldrandom}]
-\cs{PSNuseoldrandom}
-\end{definition}
-
-\begin{definition}[\DescribeMacro{\PSNrandseed}]
-\cs{PSNrandseed}\marg{n}
-\end{definition}
-This sets the seed to \meta{n} which must be a non-zero integer.
-For example, to generate a different set of random numbers
-every time you \LaTeX\ your document,\footnote{assuming you
-leave at least a minute between runs.} put the following in your
-preamble:
-\begin{verbatim}
-\PSNrandseed{\time}
-\end{verbatim}
-or to generate a different set of random numbers every year you
-\LaTeX\ your document:
-\begin{verbatim}
-\PSNrandseed{\year}
-\end{verbatim}
-
-\begin{definition}[\DescribeMacro{\PSNgetrandseed}]
-\cs{PSNgetrandseed}\marg{register}
-\end{definition}
-This stores the current seed in the count register specified by
-\meta{register}.
-For example:
-\begin{verbatim}
-\newcount\myseed
-\PSNgetrandseed{\myseed}
-\end{verbatim}
-
-\begin{definition}[\DescribeMacro{\PSNrandom}]
-\cs{PSNrandom}\marg{register}\marg{n}
-\end{definition}
-Generates a random integer from 1 to \meta{n} and stores in
-the count register specified by \meta{register}. For example,
-the following generates an integer from 1 to 10 and stores it
-in the register \cs{myreg}:
-\begin{verbatim}
-\newcount\myreg
-\PSNrandom{\myreg}{10}
-\end{verbatim}
-
-\begin{definition}[\DescribeMacro{\random}]
-\cs{random}\marg{counter}\marg{min}\marg{max}
-\end{definition}
-Generates a random integer from \meta{min} to \meta{max} and
-stores in the given counter. For example, the following generates
-a random number between 3 and 8 (inclusive) and stores it in
-the counter \texttt{myrand}.
-\begin{verbatim}
-\newcounter{myrand}
-\random{myrand}{3}{8}
-\end{verbatim}
-
-\begin{definition}[\DescribeMacro{\doforrandN}]
-\cs{doforrandN}\marg{n}\marg{cmd}\marg{list}\marg{text}
-\end{definition}
-Randomly selects \meta{n} values from the comma-separated list
-given by \meta{list} and iterates through this subset. On
-each iteration it sets \meta{cmd} to the current value and
-does \meta{text}. For example, the following will load a
-randomly selected problem from two of the listed files (where
-\texttt{file1.tex}, \texttt{file2.tex} and \texttt{file3.tex}
-are files containing at least one problem):
-\begin{verbatim}
-\doforrandN{2}{\thisfile}{file1,file2,file3}{%
-\loadrandomproblems{1}{\thisfile}}
-\end{verbatim}
-
-\section{Compatibility With Versions Prior to 3.0}
-
-Version 3.0 of the \sty{probsoln} package completely changed the
-structure of the package, but the commands described in this
-section have been provided to maintain compatibility with
-earlier versions. The only problems that are likely to occur are
-those where commands are contained within groups. This will
-effect any commands that are contained in external files that are
-outside of the arguments to \ics{newproblem} and \ics{newproblem*}.
-However, since the external files had to be parsed twice in
-order to load the problems, this shouldn't be an issue as adding
-anything other than problem definitions in those files would
-be problematic anyway.
-
-The other likely difference is where the random generator is
-used in a group. This includes commands such as
-\ics{selectrandomly}. For example, if your document contained
-something like:
-\begin{verbatim}
-\begin{enumerate}
-\selectrandomly{file1}{8}
-
-\item Solve the following:
-\begin{enumerate}
-\selectrandomly{file2}{4}
-\end{enumerate}
-
-\selectrandomly{file3}{2}
-\end{enumerate}
-\end{verbatim}
-Then using versions prior to v3.0 will produce a different
-set of random numbers since the second \cs{selectrandomly}
-is in a different level of grouping. If you want to ensure
-that the document produces exactly the same random set with
-the new version as with the old version, you will need to
-get and set the random number seed. For example, the above
-would need to be modified so that it becomes:
-\begin{verbatim}
-\begin{enumerate}
-\selectrandomly{file1}{8}
-
-\item Solve the following:
-\newcount\oldseed
-\PSNgetrandseed{\oldseed}
-\begin{enumerate}
-\selectrandomly{file2}{4}
-\end{enumerate}
-\PSNrandseed{\oldseed}
-
-\selectrandomly{file3}{2}
-\end{enumerate}
-\end{verbatim}
-
-\begin{definition}[\DescribeMacro{\selectrandomly}]
-\cs{selectrandomly}\marg{filename}\marg{n}
-\end{definition}
-This is now equivalent to:
-\begin{ttfamily}\obeylines
-\{\cs{loadrandomproblems}\oarg{filename}\marg{n}\marg{filename}\}\%
-\cs{foreachproblem}\oarg{filename}\{\cs{PSNitem}\cs{thisproblem}\cs{endPSNitem}\}
-\end{ttfamily}
-
-\begin{definition}[\DescribeMacro{\selectallproblems}]
-\cs{selectallproblems}\marg{filename}
-\end{definition}
-This is now equivalent to:
-\begin{ttfamily}\obeylines
-\{\cs{loadallproblems}\oarg{filename}\marg{filename}\}\%
-\cs{foreachproblem}\oarg{filename}\{\cs{PSNitem}\cs{thisproblem}\cs{endPSNitem}\}
-\end{ttfamily}
-
-Note that in both the above cases, a new data set is created
-with the same name as the file name.
